What it's used for

  • The AS announces 3072 IPv4 addresses across 12 prefixes and 1 IPv6 prefix, with 4 observed neighbours, indicating a small-scale access provider rather than a transit hub.
  • Traffic from this AS consists of subscriber eyeballs and small business endpoints, consistent with Fiber 23's role as a cable/DSL/ISP provider in Italy.

Classification and threat

Residential Fixed-line consumer ISP. Addresses here are homes.

Spamhaus DROP

Not on ASN-DROP The network as a whole is not listed.

No DROP prefixes None of its announced space is on the DROP prefix list.

Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 449 networks and 1,846 prefixes, as published 2026-11-03. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.

FBI IC3

No IC3 indicators Nothing from the FBI IC3 feed.

IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
